Brunneofusispora sinensis S.K. Huang & K.D. Hyde, in Phookamsak et al., Fungal Diversity: 10.1007/s13225-019-00421-w, [38] (2019)

Index Fungorum number: IF555600         Facesoffungi number: FoF04863

 

Sexual morph: Ascomata 325–370 µm diam., perithecial, solitary to scattered, immersed, eventually erumpent, globose to subglobose, uni-loculate, glabrous, dark brown to black, ostiole, papillate with long beak. Ostioles central, lined with periphyses. Peridium 20–45 µm wide, equally thick-walled, composed of 5–8 strata, of blackened pseudoparenchymatous cells, arranged in a textura angularis. Hamathecium composed of numerous, 1.5–3.5 µm wide, filamentous, septate pseudoparaphyses, embedded in a gelatinous matrix. Asci 53–110 × 9–18 µm (x̄ = 75 × 14 µm, n = 30), 8-spored, bitunicate, fissitunicate, cylindric-clavate to clavate, short pedicellate, rounded at the apex, with an ocular chamber. Ascospores 18–22 × 5–8.5 µm (x̄ = 20 × 7 µm, n = 50), overlapping 2-seriate, initially hyaline, becoming light brown to brown at maturity, broadly fusiform, 1-septate, constricted at the septum, smooth-walled, with guttules, surrounded by mucilaginous sheath. Asexual morph: Undetermined.

 

Culture characteristics: Ascospores germinated on PDA within 2 weeks at 23 °C, colony on PDA reaching 1 cm diam. after 4 weeks, irregular in shape, surface rough, with edge umbonate and well-defined margin, velvety to floccose; from above brown; from below cream, not producing pigmentation on agar medium.
